First Claim
Patent Images
1. A method for monitoring of fluid composition using a field asymmetric ion mobility spectrometer, the method comprising:
- (a) providing a first fluid sample;
(b) generating a first time-averaged ion abundance profile corresponding to the composition of the first fluid sample;
(c) providing a second fluid sample;
(d) generating a second time-averaged ion abundance profile corresponding to the composition of the second fluid sample; and
(e) detecting a change in the fluid composition by comparing the second profile to the first profile.
